To all 'whom it 'may concern:V j

Be it known that I, CHARLES W. AD'srr, a citizen of the UnitedlStates,-residin l at Owatonna, in the county of'Steele and tate ofMinnesota, yhave invented certain new and useful Improvements inSnowplows; ,andI

senger, mail and other trucks maintaining regular serviceofvariouskinds. 'It/isqu'ite important to keepthese roads open and this isquite a task in portionsi ofthe country where there is considerablesnow.

It is anobjectl offthis invention, therefore, to provide a snow plowwhich can be efficiently used on such roads to quickly clear the same ofsnowx It is a further object of the invention to p-rovide such a plowcomprising a propelled frame or vehicle having an inclined platform orsnow gathering scoop at the forward portion thereof, said platform orscoop having a rotating means therein for discharging the snow.

It is a still further object of the invention to construct said platformwith one open side and to provide a rotating plate forming part of theplatform, which plate is positively driven and provided with snowdischargeable blades.

These and other objects and advantages of the invention will be fullyset forthfin the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the different views, and in which,

Fig. 1 is a view partly in side elevation and partly in vertical sectionof the device;

Fig. 2 is a view in central vertical section of the scoop anddischarging means taken on the line 2-2 of Fig. 3; and

Fig. 3 is a plan view of the scoopand discharging means.

Referring to the drawings, the device comprises a wheeled or truck frame1, which, in the embodiment of the invention illusvrollers 5;

'-,trated, isshown as a closed vehicle'body.

-F rom the' forward part of this body or frame; an inclined platform 2 1projects forming a snow "receiving scoop and said platform is providedalong its rear endV and one side with' afvertical flange, -the otherSide of the platform vo-r scoop being left open. A p-air of frontmembers 4 extend beneath the member'2 andhave their curved llower endssecured ythereto and their rear ends connected to the'frame'l, saidmembers having pivotally connected thereto by laterally extendingpivots, small supporting Additional bracing or supporting members forthe 'platformare shown as A6 and 7 which vare connected, respectively,`to members'4 and 2. A member 8 extends between the members 4 and hassecured. thereto a vertical hollow bearing 9 Lin whichvissuitably heldand jo-urnaled a shaft 10 yhaving a plate orflange at 'its upper endsupported on 'bearing 9, to which flangeis v`riveted or Aotherwisesuitably ysecuredfa circular plate 11. yThis plate 11 is disposed l"in acircular recess in the platform 2 and is substantially flush therewith.A plurality of curved radially disposed blades 12 are struck up from aplate 11a which overlies plate v11 andis connected by rivets or othersuitable means to the plate 11. A sheave 13y is also bolted to thebottom of the plate 11 surrounding the bearin 9.

n the frame 1 orv therein is mounted a mot-or 14 of any suitable typewhich is illustrated as an internal combustion motor. A shaft 15 isvertically disposed in the members land suitably journaled in bearingstherein and carries a clutch pulley 16 driven from the motor 14 by asuitable belt 14?.y A

pulley 17 forms the other clutch member of the clutch pulley 16 and abeltk 18 passes over the pulley 17 and the sheave 13 being guided oversuitable sheaves 18a in the front portion of the member 1. The member 17is formed with a suitable clutch collar 17a and is normally urged intoengagement with the 1 mechanism.

form a rotating means for discharging the snow fromY the open side ofthe scoopY or platform 2. The member 1 and the said scoop will'bepropelled and the snow will travel up the scoop 1 and continuously comeinto engagement with the blades 12 and'be discharged at one siede of theroadway. The vehicle comprising the body 1 will, of course, be providedwith the usual variations in speeds and have the usual reversing Theplow can thus be advanced at the'desired speed according to the amountof snow encountered and the roadway can be quickly andeiiicientlycleared, The rotatingidischarge means 11 and 12 may beidrivenwhen desired and disconnected readily by the lever 20.

It will, of course, be understood that various :changes may be made inthe form, details and proportions of the parts without departingfromrthe scope of applicants invention, which, generally stated,consists in the matter shown and described and set `forth in theappended claims.

What is claimed is: e

1. A snow plow having in combination a wheeled frame, a forwardlyinclined scoop at one end'thereof having an open side, and rotatingdischarging means in said scoop for discharging the snow at said sidethe axis of said means being substantially normal to they surface ofsaid scoop.

2. A snow plow having in combination, a wheeled frame, means forpropelling the same, a forwardly inclined scoop at the front of saidframe having an open side, and a driven rotatable vaned wheel fordischarging the snow at said side, the lower edgesof the vanes of saidwheel moving parallel and in close proximity to the surface of saidscoop.

3. A snow plow having in combination, a wheeled frame, means forpropelling :the same, a forwardly inclined platform atone end of saidframe forming a scoop, a flange said frame, a circular plate mounted insaid:

platform, a discharge blade carried byv said plate, a shaft secured tosaid plate and journaled in `said bearing having its axis substantiallynormal to said platform, a sheave secured to the underside of saidplate, and

means for driving said sheave and'plate from said vehicle.

YIn testimony whereof I aix my signature.

CHARLES W. ADSIT.
